Wingtip rib positioning system and positioning device

Abstract

The invention discloses a wingtip rib positioning system and a positioning device and belongs to the technical field of aircraft digital assembling. The wingtip rib positioning system comprises a rear edge positioning base and a wingtip rib positioning device, wherein the rear edge positioning base comprises a support base and a stretching base which is arranged on the support base in the manner of extending toward a guide rail slide block mechanism; an end part of the stretching base, close to the wing root, is fixedly connected with the support base; a stretching component in the stretching base has an aluminum alloy structure; the wingtip rib positioning device is fixed at a wingtip rib end of the stretching base. The positioning system is adopted, so that the mounting efficiency of the wingtip rib is increased, the assembling stress of an external wing box is reduced and the mounting quality of the external wing box is effectively increased.

Description

technical field [0001] The invention relates to an aircraft assembly tool, in particular to a positioning device for positioning wing tip ribs in the assembly of a large aircraft outer wing box and a positioning system constructed with the positioning device. Background technique [0002] During the assembly process of the aircraft, it is usually necessary to position its components, especially the very large outer wing box, which not only needs to position and support its leading edge components and trailing edge components, but also needs to position and support the wing root ribs and wing tip ribs However, due to the large assembly plant, it is difficult to control the ambient temperature. There are temperature differences at different positions of the wing box and the temperature fluctuations in different time periods are relatively large, resulting in thermal expansion or Shrink by cold, and the size of the positioning device fixed on the foundation is usually relativel...

Problems solved by technology

[0002] During the assembly process of the aircraft, it is usually necessary to position its components, especially the very large outer wing box, which not only needs to position and support its leading edge components and trailing edge components, but also needs to position and support the wing root ribs and wing tip ribs However, due to the large assembly plant, it is difficult to control the ambient temperature. There are temperature differences at different positions of the wing box and the temperature fluctuations in different time periods are relatively large, resulting in thermal expansion or Shrink by cold, and the size of the positioning device fixed on the foundation is usually relatively stable, which makes it prone to local deformation and stress, especially the amount of expansion and contraction at different positions accumulates at the wing tip rib, which is not only difficult to install and The problem of deformation, and will accumulate a large assembly stress after assembly
